OMG, someone respectable posting on your thread :O
Lol, whatever. Your animations are pretty stiff, and you can fix that by moving every single joint you can in every frame, but still try not to get shaky. Also, you improved from your first animation a lot by the Tiger flip, but you still have much to do. I also see you are trying to work on slow-motion, there are two ways to do that, pixel-by-pixel and double framing. examples for those are:

Pixel by Pixel, move the character 1 pixel each frame when doing slow motion;

Double Framing, insert a frame every 2 frames during slow motion.
Also, so your animations don't slow down when you publish them, make your save settings look like this:

And remember to do it each time you save an animation
Also, all newbies must learn the rule of
Courtesy. I am not going to ask for it now, as I have not published anything recently, but when someone gives you a good comment (At least half as good as mine) and says Courtesy? Or some variation of that at the end of their post, they expect you to give as good of a comment on their thread thereafter.

P.S.: Also, don't use pivot 3. Pivot 2 works better and has a better feel.
